Can someone explain how to solve this problem. Since I can get 7 integers from 1st inequality 5 integers from 2nd inequality I got total number of cases of 35. Then I counted the possibilities that would be less than 4. For example x=o y can = 0, 1, 2, 3, when x=1 y=0,1,2 and so on. I came down to 10/35, but the answer is 1/3 .
